Early Selection Effect
Early Selection Effect
Attention filters out irrelevant stimuli early in processing. Task-relevant stimuli pass through, distractors are largely excluded.
Late Selection Effect
Late Selection Effect
Attention filters out irrelevant stimuli later, after initial processing. Distractors are processed, but their influence on behavior is blocked.

Study Notes
Attention
- Attention is the ability to focus on specific stimuli or locations
- Selective attention: focusing on one specific location, object, or message
- Overt attention: shifting attention by moving the eyes
- Covert attention: shifting attention without moving the eyes (e.g., seeing something "out of the corner of the eye")
- Divided attention: attending to multiple things simultaneously (can be overt, covert, or a combination)
Early Studies: Results & Consequences
- Limited capacity: inability to identify multiple messages at once
- Effective selectivity: ability to identify one message when differences are in physical characteristics (e.g., different tones of voice). Difficulty identifying messages when differences are contextual
Selective Attention as Filtering
- Cherry's Dichotic Listening Experiment:
- Participants listened to different messages in each ear and were instructed to shadow (repeat aloud) one message.
- Results: People could attend to only one message.
- Information from the unattended ear was minimally processed (crude characteristics like gender, tone were noted).
Broadbent's Early Selection Model (Bottleneck)
- Sensory memory: holds incoming information briefly.
- Filter: selects the attended message based on physical characteristics (e.g., tone, pitch, speed of speech).
- Detector: processes the attended message, extracting meaning.
Treisman's Attenuation Model
- Selection occurs in two stages:
- Pre-attentive analysis: analyzes all incoming information, including unattended, but at low intensity (attenuated).
- Dictionary unit stage: critical, meaningful information is passed through a dictionary unit containing words with thresholds for activation (e.g., person's name).
Controlling Distractors
- Early selection: focuses on task-relevant stimuli, excluding distractors.
- Late selection: focuses on task-relevant stimuli, preventing distractors from interfering with behaviors or memory.
Cognitive Resources, Cognitive Load, & Task-Irrelevant Stimuli
- Cognitive resources: limited capacity for cognitive tasks.
- Cognitive Load: amount of resources needed for a task.
- Low load: easy, well-practiced tasks.
- High load: difficult, less-practiced tasks.
- Distractor effects: more significant with low cognitive load conditions than high ones.
- Flanker Compatibility Task: demonstrates attentional effects with compatible and incompatible flankers.
Divided Attention
- Automaticity: occurs with well-practiced tasks allowing for processing without conscious awareness.
- Divided attention: ability to process multiple tasks at once.
- Processing limitations: some cognitive tasks cannot be processed automatically.
- Allocation of resources: the amount of cognitive resources/attention focused on a task.
Stroop Effect
- Task-irrelevant stimuli (e.g., words with colors): automatic responses to highly practiced tasks can hinder processing and response times.
Attention & Visual Perception
- Inattentional blindness: difficulty detecting unexpected or unimportant changes.
- Visual perception: attention is focused on one thing at a time which affects visual perception.
Change Detection
- Change detection: ability to notice changes in scenes.
- Importance of attention: attention is necessary for noticing changes.
Eye Movements & Attention
- Eye fixations: brief pauses in eye movements.
- Saccadic eye movements: rapid movements between fixations.
- Stimulus salience: perceptual features that capture attention.
- Meaning attracts attention: top-down factors (prior knowledge and goals) affecting eye movements.
Attention in Social Situations (Autism)
- Importance of attention for social interactions.
- Difficulties in social situations: decreased attention to others, difficulties with social cues and understanding.
